Straight from the Xotic Effects Custom Shop, the BB Preamp MB takes the world renowned BB Preamp to a whole new level. Along with the incredible boost, eq, and gain controls of the stock BB Preamp, the BB Preamp MB features an adjustable mid-frequency boost or cut. This control allows the user to dial in a variety of tones from one overdrive pedal. It's perfect for adding that extra bite to your lead tone, or for a scooped rhythm sound, and is great through any amp you could pair it with. The BB Preamp MB features a sleek, brushed aluminum housing and unique colored scripting. Like every Xotic Effects pedal it is true bypass and is made with the absolute highest quality components. It can be powered with an optional power adaptor or by 9V battery.
